Related Art

In 5G systems, Enhance Mobile Broadband (eMBB) and Ultra Reliable and Low Latency Communication (URLLC) are two typical service types. A new Modulation and Coding Scheme (MCS) table has been defined for requirements of lower target BLER (10{circumflex over ( )}−5) of URLLC services in the 3rd Generation Partner Project (3GPP) New Radio (NR) Release 15.

In order to support URLLC services of higher requirements, for example, higher reliability (eg. target BLER is 10{circumflex over ( )}−6), lower latency (eg. 0.5-1 ms), etc., the 3GPP Radio Access Network (RAN) #80 session had approved a Study Item (SI) of URLLC enhancement of NR Release 16, in which enhancements to Hybrid Automatic Repeat reQuest (HARQ) feedback/Channel State Information (CSI) feedback are a key point to be studied.

SUMMARY

The inventor finds through researches that Uplink Control Information (UCI) includes HARQ/CSI, when one PUCCH reserved to a UCI is not orthogonal to a PUSCH in time domain, in order to support the transmission of higher reliability in NR Release 16, how to transmit a UCI is a key problem to be reconsidered.

In view of the above problems, the disclosure provides a solution. It should be noted that the embodiments of the disclosure and the characteristics in the embodiments may be mutually combined arbitrarily if no conflict is incurred.

The disclosure provides a method in UE for wireless communication, wherein the method includes:

receiving a first signaling, the first signaling being used for determining a first time-frequency resource group, and the first time-frequency resource group being reserved to transmission of a first bit block; and

transmitting K radio signals and the first bit block in K time-frequency resource groups.

Herein, time-domain resources occupied by the first time-frequency resource group are overlapping with time-domain resources occupied by at least one of the K time-frequency resource groups, and any two of the K time-frequency resource groups are orthogonal in time domain; the K radio signals are transmitted in the K time-frequency resource groups respectively, and the first bit block is transmitted in only K1 time-frequency resource group(s) among the K time-frequency resource groups; the first signaling corresponds to a first type or a second type, and whether the first signaling corresponds to the first type or the second type is used for determining the K1 time-frequency resource group(s) from the K time-frequency resource groups; the K is a positive integer greater than 1, and the K1 is a positive integer not greater than the K.

In one embodiment, the problem to be solved by the disclosure is: how to enhance the transmission of a UCI when a PUCCH is not orthogonal to a PUSCH in time domain, in view of the requirements of higher reliability in NR Release 16.

In one embodiment, the problem to be solved by the disclosure is that: in current standards, when a PUCCH reserved to transmit a UCI is not orthogonal to one PUSCH in time domain, the transmission of the UCI is changed onto the PUSCH. In NR Release 16, one PUSCH probably occupies few time-domain resources, for example, one or several multicarrier symbols, there might be multiple PUSCHs transmitted in one same timeslot of one same carrier or in one same subframe, and the multiple PUSCHs may be multiple repeated transmissions of one Transport Block (TB) or may be transmissions of multiple different TBs; when a UCI is not orthogonal to at least one of the multiple PUSCHs, on which of the PUSCHs the UCI is to be transmitted is a key problem to be reconsidered.

In one embodiment, the problem to be solved by the disclosure is that: in current standards, when a PUCCH reserved to transmit a UCI is not orthogonal to one PUSCH in time domain, the transmission of the UCI is changed onto the PUSCH. In NR Release 16, one URLLC PUSCH probably occupies few time-domain resources, for example, one or several multicarrier symbols, there might be multiple URLLC PUSCHs transmitted in one same timeslot of one same carrier or in one same subframe, and the multiple URLLC PUSCHs may be multiple repeated transmissions of one TB or may be transmissions of multiple different TBs; since an eMBB UCI and a URLLC UCI have different requirements on transmission latency, when a UCI is not orthogonal to at least one of the multiple URLLC PUSCHs, a service type corresponding to the UCI needs to be considered when determining on which of the PUSCHs the UCI is to be transmitted.

In one embodiment, the essence of the above method is that: the first time-frequency resource group is a PUCCH, the K time-frequency resource groups are K PUSCHs, the first bit block is a UCI, the PUCCH is not orthogonal to at least one of the K PUSCHs, the first type corresponds to URLLC services, and the second type corresponds to eMBB services. The above method has the following benefits: on which of the PUSCHs the UCI is to be transmitted is determined according to the service type corresponding to the UCI.

According to one aspect of the disclosure, the above method is characterized in that: when the first signaling corresponds to the first type, the K1 time-frequency resource group(s) is(are) K1 earliest time-frequency resource group(s) in time domain among K2 time-frequency resource group(s) respectively; each of the K2 time-frequency resource group(s) is one of the K time-frequency resource groups, and the K2 is a positive integer not less than the K1 but not greater than the K; the K2 is equal to the K and the K2 time-frequency resource groups are the K time-frequency resource groups respectively; or, the K2 time-frequency resource group(s) is(are) all time-frequency resource groups overlapping with the first time-frequency resource group in time domain among the K time-frequency resource groups.

In one embodiment, the essence of the above method is that: K2 time-frequency resource group(s) is(are) K2 PUSCH(s) among the K PUSCHs, and a URLL UCI is transmitted on K1 earliest PUSCH(s) in time domain among the K2 PUSCH(s). The above method has the following benefits: the transmission low latency of the URLLC UCI is guaranteed.

According to one aspect of the disclosure, the above method is characterized in that: when the first signaling corresponds to the second type, the K1 time-frequency resource group(s) is(are) K1 latest time-frequency resource group(s) in time domain among K3 time-frequency resource group(s) respectively; each of the K3 time-frequency resource group(s) is one of the K time-frequency resource groups, and the K3 is a positive integer not less than the K1 but not greater than the K; the K3 is equal to the K and the K3 time-frequency resource groups are the K time-frequency resource groups respectively; or, the K3 time-frequency resource group(s) is(are) all time-frequency resource groups overlapping with the first time-frequency resource group in time domain among the K time-frequency resource groups.

In one embodiment, the essence of the above method is that: the K time-frequency resource groups are K URLLC PUSCHs respectively; in order to guarantee the transmission high reliability of the URLLC PUSCH, the K URLLC PUSCHs are repeated transmissions of one same TB respectively, the K3 time-frequency resource group(s) is(are) K3 PUSCH(s) among the K URLLC PUSCHs, and an eMBB UCI is transmitted on K1 latest PUSCH(s) in time domain among the K3 PUSCH(s). The above method has the following benefits: when K3 is greater than K1, the eMBB UCI does not affect the transmission of the (K3-K1) earliest PUSCH(s) among the K3 PUSCH(s), and a receiving terminal may parse the TB relatively early based on multiple repeated transmissions; therefore, this method is beneficial to the transmission low latency of the URLLC PUSCH.
